Revelation 17:12
Patriarchal Greek New Testament (1904) · Berean Standard Bible
καὶ τὰ δέκα κέρατα ἃ εἶδες δέκα βασιλεῖς εἰσιν, οἵτινες βασιλείαν οὔπω ἔλαβον, ἀλλ᾽ ἐξουσίαν ὡς βασιλεῖς μίαν ὥραν λαμβάνουσι μετὰ τοῦ θηρίου.
The ten horns you saw are ten kings who have not yet received a kingdom, but will receive one hour of authority as kings along with the beast.
